Abstract: An improved roller device includes a plurality of segments, wherein the plurality of segments is configured to form a tubular shape. In addition each of the plurality of segments are coupled to neighboring segments of the plurality of segments and each of the plurality of segments include a first edge and a second edge, wherein the first edge is opposite the second edge. Each segment includes a plurality of protrusions on each respective edge for interfacing with a respective complementary edge with complementary protrusions of a neighboring segment. The roller device also includes a coupling mechanism for coupling the first edge of a segment to a second edge of a first neighboring segment and coupling the second edge of the segment to a first edge of a second neighboring segment, wherein the coupling mechanism allows the plurality of segments to convert from a first position to a second position.
